A remark on worldsheet fermions and double-scaled matrix models
Anton Kapustin
We provide a heuristic explanation for the emergence of worldsheet fermions in the continuum limit of some matrix models. We also argue that turning on Ramond-Ramond flux confines…
Topological sigma-models with H-flux and twisted generalized complex manifolds
Anton Kapustin, Yi Li
We study the topological sector of N=2 sigma-models with H-flux. It has been known for a long time that the target-space geometry of these theories is not Kahler and can be describ…
On the relation between open and closed topological strings
A. Kapustin, L. Rozansky
We discuss the relation between open and closed string correlators using topological string theories as a toy model. We propose that one can reconstruct closed string correlators f…
Fatgraph expansion for noncritical superstrings
Anton Kapustin, Arvind Murugan
We study the fatgraph expansion for the Complex Matrix Quantum Mechanics (CMQM) with a Chern-Simons coupling. In the double-scaling limit this model is believed to describe Type 0A…
Gauge theory, topological strings, and S-duality
Anton Kapustin
We offer a derivation of the duality between the topological U(1) gauge theory on a Calabi-Yau 3-fold and the topological A-model on the same manifold. This duality was conjectured…
